“The blood is verv pale and watery; a moderate poikiloc^tosis is present; there 
are no nucleated red corpuscles and no malaria organisms present. The blood count 
shows: Eed corpuscles, 1,120,000; hemoglobin, 18 per cent; leucoc\*tes, about 4,000; 
polymorphonuclear, 52 per cent; eosinophiles, 26.8 per cent; small mononuclear, 14 
per cent; large mononuclear, 4.4 per cent; transitional, 2.8 per cent. 
“One month later, the patient meantime having been taking arsenic and iron, the 
blood count was as follows: Eed corpuscles, 1,450,000; hemoglobin, 22 per cent; leu- 
cocytes, 2,000; polymorphonuclear, 61 per cent; eosinophile, 18.2 per cent; small 
mononuclear, 16.4 per cent; large mononuclear, 3.2 per cent; transitional, 1.2 per 
cent; no nucleated red cells. 
“There had been practically no change in the patient's condition. The Ever and 
spleen were as in the former note, and the dyspncea was marked. Numerous typical 
ovums of the Uncinaria were present in the stools, but no adult forms were seen. 
After the usual thymol treatment about 60 adult worms were found. They resembled 
in all respects Uncinaria duodenalis, and were identified by Dr. Stiles as the Old 
IVorld hookworm. The ovums present were in the progress of segmentation, 4 to 12 
cells being visible. Xone were seen containing an embryo, as frequently occurs in 
the form Uncinaria americana, described by Dr. Stiles. 
“Blood examinations, ten and twenty days after the th^miol treatment was begun, 
showed the following counts:

“The general condition is also improving rapidly, although the parasites are not 
entirely eliminated, as an ovum is still occasionally found in the stools. ’ ’

Cases found on microscopic examination by Stiles, Garrison. Eansom, and Steven-

Counn* a condition'of “bloat' ’ and anemia which is usually attributed to dirt-eating, 
and which cori'esponds in general to the conditions described in this paper.
